` -10 claims.- (01924-537) f Our invention relates to belt splicer'sforfasteners and `is, designed particularly for use-inJseJ- curing theendsof power belts of the .typehaving a series of transverse blocks thereonWithfrid- 5 tion `pads on the ends of the blocks or belts of ,the typehaving edges` Whichrictionallyiengage Withfdriving or driven pulleys. .ly

' An Vobject of the invention is to provide a, belt sfastening which maybe readily manipulatediin I positions Which are diilicult ofaccess.'

A further object is to provide a splice of light ,construction andone'which will providezastrong lunion to :render the belt continuousiandwhich :mayxbeapplied to the belt While the same lis re- 175 V:moved fromthe transmission so Vthat it Will ibe necessary only vto Vclamp thepartstogether after thebelt has been placed in positionon thetrans- .missionmechanism. l

The position of the splice shown in Figure 5will illustrate the ease with which the device may be used.

One important practical advantage of these splicing plates is that theyare much lighter than splicing blocks of this general type now in useand are, therefore, particularly adapted for use with belts of the kindshown. Y

In Figures 6 and 7 Ithe splicing blocks are shown adapted to a differentform of belt. Belts generally known as of the V-type have commonly beenused heretofore as automobile fan belts. Belts of this type have morerecently been made in much larger sizes for transmitting power and havebeen made in almost any lengths by using a number of belts to form thedriving transmission. In some work there are specially molded belts usedin which the width is Ymuch greater than the thikness. .These belts'havetheir frictional engagement with the pulley on the edges of the belts.In Figures 6 and 7 we have shown means for splicing the ends of some ofthese belts together. As shown in Figure 6 plates'29 -are secured byrivets 3l to plates 3on .the opposite side of the belt. Plates 32 aresecuredby nuts 34 to plates 33 on the opposite side of the belt, theplates 32 being oppositely arranged from the plates 29. Bolts 35 passthrough these plates and through the ends of the belt and secure theplates together. This forms a simple, light but effective splice for'belts of this type.

It will be obvious to those skilled in theart that various changes maybemade in our device without departing from the spirit of the inventionand therefore we-do not limit ourselves to what is shown in the drawingsand ydescribed in the specification, but only as indicated by theappended claims.v Y

Having thus fully described our said invention, what `we Aclaim as newand desire to secure by Letters Patent, is: Y

1. In a belt splicer the combination lwith a belt and a belt blockassociated therewith of a pair of plates .at the meetingv ends Vof thebelt, said plates being secured to the ends of the belt and havingcooperating elements engageable with eachother for taking some of lthepull on the belt, and a bolt passing through said plates and throughsaid belt block. v

2. The combination with a'belt and belt blocks adapted foruse inconnection with variable speed transmissionv mechanism of a pair ofplates fixed to the .belt adjacentthe ends thereof, the end of one platebeingsecured to theend of the belt, the Vother end of the plate 'havinga cut out portion, the other, plate beingsimilarly. formed but arrangedoppositely to the first plate, short plates secured to the oppositesides .of the ends of the belt and engagingthe lcutfout .portion on theother plate, thelmeans for fastening'l said plates to the belt alsoengaging the plate-on `the other end of the belt for sustainingsome ofthepull on the belt. y A

3. In a belt splicerthe combination with a. belt and a belt blockassociated therewith of a pair of plates securedto 'the ends of saidbelt, said plates being secured to theends of said belt and to the saidblocks to permit'flexing of the belt at the spliced joints'ubstantiallyasfreely as at other places on thebelt.. Y

4. A belt splicer for a belt having a plurality of transverse blocksthereon, comprising apair of plates secured to the ends ofA thebelt,means for securing said plates together and for securing the adjacenttransverse block to the belt, said securing means passing through thesaid plates and through said transverse block.

5. A belt splicer of the kind described comprising a pair of plates,said plates being formed so as to have flat portions lying in two offsetparallel planes, means for securing the ends of said plates to adjacentends on the belt, the offset parallel planes providing recessesoppositely arranged and on opposite sides of the belt, a pair of platessecured on the ends of said belt and adapted to seat insaid recesses,the free ends of said prior named plates being perforated to receive theheads of the securing means for the other ends of the plates, and meanspassing through said plates for securing transverse blocks on said belt.

6. A splicer for a variable speed transmission belt of the kinddescribed comprising a pair of blocks adapted to be secured to said beltat the free ends of the belt, said blocks having friction pads on theiropposite ends to provide a friction drive'between the belt and thedriving means or the driven pulley, long and short plates secured toeach end of said belt, the free ends of the long plates having cut outportions adapted to receive a short plate secured on the other end ofthe belt, rivets securing said plates to the ends of said belt, theheads of said rivets being engageable in sockets in the free end of theopposite long plate to form a driving engagement with the plate.

7. In a belt splicer, the combination with a belt and a belt blockassociated therewith, of a pair of plate members at the meeting ends ofthe belt, and means passing through said members and block to transmitthe tension of the belt and to hold the members in an assembledrelation.

8. The combination with a belt and belt blocks attached for use inconnection with variable speed transmission mechanisms, of a pair ofmembers fixed to the belt adjacent the ends thereof and means forsecuring said members to the belt, said means having projectionsinterlocking with the member secured to the other end of the belt.

9. In a belt splicer the combination with a belt and a belt blockassociated therewith, of plates adjacent the severed ends of the belt,one of said plates being recessed to fit a plate on the opposite end ofthe belt, and means for securing said plates to said belt, said meanshaving projections which interlock with openings in the recessed side ofsaid plate.

10. In a belt of the V-type, the combination of splicing plates on theends of the belt, one of said kplates consisting of a flat plate securedto the end of the belt, the other plate having a cut-out portion adaptedto receive the first named plate and secured to and on the same side ofthe belt, corresponding plates being secured in alternate ar'- rangementon the other side of the ends of the belt and fastening means passingthrough said plates and the ends of said belt to secure said plates toeach other and to the belt and to take part of the pull of the belt.
